This paper describes an architecture for differentiation of Quality of Service in heterogeneous wireless-wired networks. This architecture applies an “all-IP” paradigm, with embedded mobility of users. The architecture allows for multiple types of access networks, and enables user roaming between different operator domains.

Configuring and Testing Your Network. Learning Objectives
Upon completion of this chapter, you will be able to:
Define the role of the InternetworkOperating System (IOS).
Define the purpose of a configuration file.
Identify several classes of devices that have the IOS embedded.
Identify the factors contributing to the set of IOS commands available to a device.
Identify the IOS modes of operation.
Identify the basic IOS commands.
Compare and contrast the basic show commands.

Wireless sensor nodes are small, embedded computing devices that interface with sensors/
actuators and communicate using short-range wireless transmitters. Such nodes act
autonomously, but cooperatively to form a logical network, in which data packets are routed
hop-by-hop towards management nodes, typically called sinks or base stations. A Wireless
Sensor Network (WSN) comprises of a potentially large set of nodes that may be distributed
over a wide geographical area, indoor or outdoor

Overview of this seminar
This introductory seminar will:
• Provide an overview of this course
• Introduce the 8051 microcontroller
• Present the “Super Loop” software architecture
• Describe how to use port pins
• Consider how you can generate delays (and why you might
need to).Overview of this course
This course is concerned with the implementation of software (and
a small amount of hardware) for embedded systems constructed
using a single microcontroller.

This course is primarily concerned with the implementation of
software (and a small amount of hardware) for embedded systems
constructed using more than one microcontroller.
The processors examined in detail will be from the 8051 family.
All programming will be in the ‘C’ language
(using the Keil C51 compiler)

Nowadays, embedded systems - computer systems that are embedded in various
kinds of devices and play an important role of specific control functions, have
permeated various scenes of industry. Therefore, we can hardly discuss our life or
society from now on without referring to embedded systems. For wide-ranging
embedded systems to continue their growth, a number of high-quality fundamental
and applied researches are indispensable.
